to this time is the limitation on aircraft maneuverability (2 g's). Data of 

 this type are usually obtained from simulation studies of aircraft-pilot- 

 display performance. 



The analysis procedure to determine the probability of conversion is 

 indicated by the flow diagram shown in Fig. 2-50. As an example of how 

 such a calculation might be made, we may consider the following case.
